  • Patent number: 10374735
    Abstract: A counter is synchronized with a counter within a communication device and measures, as a first count value, a timing before a PTP packet is input to a processing unit that performs processing on the PTP packet. A multiplexing unit multiplexes the first count value into the PTP packet. The counter measures, as a second count value, a timing when processing by a processing unit that performs processing on the PTP packet is completed. A count extraction unit extracts the first count value from the PTP packet. A modification unit modifies a correction field by calculating a modification value based on the second count value, the first count value, and a value of the correction field within the PTP packet, the value of the correction field indicating a total amount of delay in a relay device.

  • Patent number: 10349341
    Abstract: A station makes a unidirectional announcement (that is, an indication, notification or advertisement) of types of services that are available to devices in or via a wireless network, for example, a wireless local area network (WLAN). The announcement is receivable by mobile devices within radio communication range of the wireless network that are in the pre-associated state, because the announcement is conveyed using low-level layer 2 frames. A mobile device that receives such a layer 2 frame may determine the announced service type or types from the received layer 2 frame. The mobile device may determine whether it can make use of any of the announced service type or types. The mobile device may provide results of the determination to a network selection algorithm implemented at the mobile device.

  • Patent number: 10327186
    Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.

The method includes: performing real-time estimation according to time domain information of M downlink transmit signals, to obtain a first intermodulation interference signal; and cancelling, according to the first intermodulation interference signal, intermodulation interference generated by the M downlink transmit signals in an uplink receive signal, where M is an integer greater than or equal to 2, and the M downlink transmit signals are baseband signals that are transmitted on M carriers and that are not combined. Based on the foregoing solutions, the actually generated intermodulation interference can be effectively cancelled, thereby reducing intermodulation interference and improving system performance.

  • Patent number: 10250343
    Abstract: A technique for measuring Reference Signal Received Power (RSRP) is provided. The RSRP is measured based on Cell-specific Reference Signals (CRSs) provided by cells (102, 104) of a mobile telecommunications network (100). The CRSs of at least two of the cells overlap in time and frequency. As to a method aspect of the technique, a time offset for sub-frames received from the at least two cells is determined. The overlapping CRSs are received for a group of sub-carriers. A coarse channel state is estimated for each of the at least two cells by multiplying the received overlapping CRSs with a function of phase-shifted CRSs. The phase-shifted CRSs of different sub-carriers in the group include a phase-shift that corresponds to the determined time offset. The RSRP is measured for each of the at least two cells based on the estimated coarse channel state.

  • Patent number: 10230849
    Abstract: A Voice over Internet Protocol (VoIP) apparatus or system includes a call control agent that is configured and arranged to perform a number of functions. The call control agent is configured to receive a connection request for a VoIP call and then accesses a list of media-relay servers (MRSs) that are located at geographically disparate locations relative to one another. The call control agent can execute a selection algorithm that processes variables for the MRSs in the list. In response to the selection algorithm, the call control agent is configured to select a particular MRS from the list. In response to the selection, the call control agent can then direct an endpoint to route audio media for the VoIP call through the particular MRS. The call control agent also is configured to maintain a call state for the VoIP call while the voice media is routed through the particular MRS.
